Overview: Fiber pigtailed Fabry-Perot etalons are optical devices used as narrow bandwidth filters with transmission peaks uniformly spaced in the frequency domain. They consist of a solid or air gap etalon, collimating lenses, and input/output fibers. These etalons are superior to fiber-based versions due to better spectral resolution and constant Free Spectral Range (FSR).

Applications: These etalons are used in telecom systems as narrow band filters to lock a laser cavity on a fixed frequency and as a frequency reference according to the ITU grid. They are suitable for optical telecommunication, optical sensing, and other applications.

Customization: All specifications can be customized upon request.
